SAFETY-PIN.

SPECIFICATION forming part of Letters Patent No. 236,149, dated January 4, 1881.

Application filed March 4, 1880. (No model.)

To all whom it may concern Be it known that I, HENRY O. FIELD, of Providence, county of Providence, and State of Rhode Island, have invented a new and useful Improvement in Safety-Pins; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, forming a part of this specification.

This invention relates to that class of pins known as safety or diaper pins; and it consists in providing the head or shield with a guide, and the novel arrangement of attaching the head securely and without solder to the In the accompanying drawings, Figure 1 represents a perspective view of the pin complete. Fig. 2 is a view of the pin detached from the head, and shows the corrugation near the unsharpened end. Fig. 3 is the headblank, cut from sheet-stock. Fig. 4-. represents the head or shield after having been drawn up in suitable dies, and Fig. 5 is an end view of same. Fig. 6 is a section of Fig. 1 on line Similar letters of reference indicate corresponding parts.

The shield or head-blank B, from which the head is formed, is a parallel-sided piece of sheet metal with circular ends, and provided on both sides and near one end with projections O. Said projections, after the blank is drawn or pressed in dies, forms the guide, as shown in Figs. 1 and 4. The object of the guide 0 is to prevent the sharpened end of the pin from too readily passing entirely through the shield when the pin is being used.

The pin A is provided nearits unsharpened end with one or more corrugations, as shown at a, Fig. The object of this corrugation or bend is to prevent the shield B from turning on or being drawn off the pin when the shield is properly swaged around said corrugation.

What I claim, and desireto secure by Letters Patent, is-

In a safety-pin consisting of a pin provided with a shield to protect its point, the guide 0, substantially as shown, and for the purpose specified.
